OK, exactly what cards do you have in mind, what will you be using them for, what will you be using them on, TV/Monitor etc etc and at what resolution.
+1 for that man, the key is what you are going to use it for.
eg, if you have the PC in your living room and use your pc for mainly playing movies and games that everyone in the room is going to like then i would but HDMI higher on the list.
If you are on big screen monitor/LCD in your bedroom with seperate hifi or speakers connected to the sound card on your PC then DVI makes more sence.
As i keep trying to explain to people at work about IT and electronic the answer is never straight forward and dependent on may factors.
